Abstract: 836,754. Making composite wire. STANDARD TELEPHONES & CABLES Ltd. Aug. 15, 1958, No. 26294/58. Class 83 (2). [Also in Group XXXVI] A cat's whisker for point contact semi-conductor devices comprises a wire of good electrical and heat conductive properties and of some resilience, e.g. silver, gold, aluminium, copper, having a diameter between 0.002 inch and 0.007 inch, and containing along the whole or part of its length a substantially concentric core of tungsten of diameter between 0.00005 inch and 0.0005 inch. The whisker may be produced by drawing or rolling down a tubular wire 21 into tight contact with a tungsten core 22 which may extend along the whole length of the wire or, as shown, occupy an end portion of it; in the latter case, the part of the wire which has no core may be further drawn or rolled so as to close the bore behind the core. Alternatively, a core may be inserted in a blind bore in one end of the wire, which is then rolled or drawn down on to the core. At one end of the wire the core is exposed by etching to form a tip 23 for establishing a rectifying contact with a semi-conductor body.

Title: Synthesis of carbazole
Inventor: GROTTA HENRY MONROE
Filed: 1959-07-31
Abstract: Diphenylamine is catalytically cyclodehydrogenated in the vapour state by contacting with a catalyst, consisting of platinum or palladium supported on silica or aluminia or on a mixture of these, in the absence of air or oxygen and at a temperature of not less than 375 DEG  C. to give carbazole.  The presence of steam and/or hydrogen in the reaction vessel is advantageous and an inert gas such as nitrogen may also be present.  If desired, the process may be conducted as a cyclic operation, the unconverted diphenylamine being recycled to the reaction vessel.  The weight-hourly-space velocity, i.e. the ratio of the number of parts by weight of diphenylamine per hour introduced into the reaction zone to the number of parts by weight of catalyst preferably does not exceed 0.3.

Abstract: 617,128. Casting composite articles. SHEEPBRIDGE STOKES CENTRIFUGAL CASTINGS CO., Ltd., and STOKES, J. E. Sept. 2, 1946, No. 26397. [Class 83 (i)] Centrifugal casting- machines.-In a method of making composite metal articles, particularly brake drums, wherein a layer of metal is centrifugally cast onto a foundation 3 of another metal, the foundation is preheated in situ on the casting machine by a high frequency induction coil 2, the heating current is switched off and the lining is cast. The foundation 3 is clamped by a nut 15 to a connector 6 in the form of a tubular boss screwed into the end of a rotatable shaft 1 coaxial with the coil 2, which overhangs the foundation 3 at each end to ensure that the full induced current flows through the whole length of the foundation. The considerable clearance between the coil 2 and the foundation 3 provides a loose electromagnetic linkage which is necessary to prevent the induced currents concentrating on the outer surface only of the foundation 3, which may also be rotated during preheating, the time of which is prolonged, to ensure even heating. Suitable fluxes may be used to ensure satisfactory welding of the two metals.
